Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method for filtering information, a method, a device, and a system for processing forwarding information. Background Art With the rapid development of information and communication technologies, various terminals can transmit various information in the network anytime and anywhere. In this context, spam is also coming. These spam messages include various erotic videos, pictures, literature and other "vulgar content", gambling, fraud, fraud and other content that violates ethics, laws and regulations, and embarrassing and bad evaluations of other online users. This information not only plagues the lives of the broad masses of the people, but also causes people's spiritual losses. Therefore, it is imperative to solve the problem of spam in the network. At present, there are two main methods for processing spam, which are based on the method of user blacklist filtering and the method of matching keywords and features. The main strategy of the former is: the user records the body of the spam in advance (such as the initiator of spam) and puts it in the restricted list, but this method occurs after the spam has been successfully sent and may need to be received. The party feedbacks the corresponding information to determine that the information is spam. In addition, since the blacklist of a single user is often incomplete, there is no ability to process the changed spam subject. The latter's main strategy is: Pre-establish a feature database of spam, extract the keywords or features in the information when new information is received, and compare the keyword or feature with the feature database to determine Whether this information is spam or not, the shortcoming of this method is that the accuracy is not high, it is easy to cause misjudgment and the efficiency is relatively low. In view of the low efficiency of filtering spam in the related art, an effective solution has not yet been proposed. SUMMARY OF THE INVENTION The present invention provides a method for information filtering, a method, device, and system for processing forwarding information to at least solve the problem of low efficiency of filtering spam in the related art.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The embodiment of the present invention considers a method for filtering spam based on a user's own blacklist or filtering rule (also referred to as a spam processing rule), which is easy to cause misjudgment and has low efficiency of filtering spam, and provides a kind of Method of information filtering, processing method of forwarding information, devices (such as client devices and servers), and systems. The details will be described below by way of examples. The embodiment provides a method for filtering information, which can be implemented on the client, as shown in the flowchart of the information filtering method shown in FIG. 1 , the method includes the following steps (step S102 - step S106 ): Step S102 , the client The terminal obtains the setting information of the third party to block the spam; wherein the third party is one or more devices other than the client; Step S104, the client updates the locally stored setting information according to the obtained setting information; Step S106 When the client receives the network information, the client filters the network information by using the updated setting information. Through the above steps, the client obtains the setting information of the third party intercepting the spam and updates the locally stored setting information, which is usually added to the locally stored setting information. When the network information is received, the client filters the network information by using the updated setting information, which solves the problem of low efficiency of filtering the spam in the related art, which expands the setting information of the client and improves the filtering of the spam. Success rate to enhance the user experience. Step S102 can acquire setting information according to the set period to achieve the purpose of updating the local setting information in a period, and improve the efficiency of updating the local setting information. The setting information of the third party intercepting the spam obtained by the client may be a blacklist and/or a spam processing rule. The blacklist mechanism filters the sender of the information. When the blacklist is used, it detects whether the sender identifier of the received message is in the blacklist, so as to determine whether it is spam. Spam processing rules Generally, the content of information is filtered. The spam processing rules can be the filtering conditions of spam, the filtering rules of spam, and the conditions for determining spam. For example, a spam signature database (such as key text, graphics/images, sounds, etc.) is built. The signature database stores common spam features/keywords. When the client receives new information, the client first extracts The information feature/keyword in the information is compared with the feature database to determine whether the information is spam. Or the client detects the received message Whether it contains information features/keywords in the spam signature database to determine whether it is spam. If it is spam, the spam is filtered and intercepted, and is not directly displayed to the user. The spam information can be deleted or stored in a special area. The above client obtains setup information from one or more other devices, which may be a server or a designated client. The client may obtain setting information of the third party intercepting the spam from the server, and the third party may include at least one of the following: a client on the network, a network user, and a server on the network. For example, the Weibo client subscribes to the garbage disposal rules provided by a security software company through the Weibo server, and can obtain the garbage disposal rules provided by the security software company server and can be updated regularly. The client on the network can be a business client of the network user, such as a QQ client, an email client, a mobile terminal client, and the like. The client can share the setting information of the third party to intercept the spam. For example, the QQ user obtains the setting information of the QQ friend client specified by the user through the client. The client expands the blacklist by sharing the blacklist of the third party, and expands the blacklist to more comprehensively process spam. The client extends the spam processing rules in the same way as the blacklist extension. The expanded blacklist and/or spam processing rules can be stored locally, and the extended blacklist is stored locally. The process flow is as shown in FIG. 2: Step S202: The client requests the server to obtain a third-party blacklist. Step S204 The server responds to the third-party blacklist of the request to the client. In step S206, the client adds the obtained third-party blacklist to the locally stored extended blacklist. The expanded blacklist can be used to filter spam. The specific method of filtering can be solved by using existing technical methods, and will not be described here. Similarly, the same is true for the processing process in which the expanded spam processing rules are stored locally, and will not be described here. When the above-mentioned local setting information is blacklist and spam processing rules, the client filters the received network information by using the updated setting information: First, the client detects whether the sender of the network information is blacklisted. Secondly, if the sender of the network information is in the blacklist, it is determined that the network information is spam. If the sender of the network information is not in the blacklist, the client detects whether there is any garbage in the network information. The keyword matched by the information processing rule; further, if the network information has a keyword matching the spam processing rule, the client determines that the network information is spam. For network information that cannot determine whether it is garbage information, it is usually simply processed according to normal information, or prompting the user to process, or detecting whether the information sender is in the white list, thereby judging whether it is friend information or strange information. If the client receives the network information forwarded by the forwarding party, it is assumed that the original sender of the network information is located in the blacklist of the client, and the forwarder is not in the blacklist. At this time, it is easy to cause a false positive, and the garbage is not filtered out. Information, in this case, the identifier of the forwarder and the identifier of the original sender may be carried in the network information, and the client detects whether the identifier of the forwarder and/or the identifier of the original sender is in the blacklist of the client, if forwarding If one of the identifier of the party and the identifier of the original sender is in the blacklist, it is determined that the sender of the network information is in the blacklist, and the network information is determined to be spam, and the spam is filtered out. If the network information received by the client is the network information forwarded by the sender, the method further includes: adding, by the sender or the server, the sender identifier and the original sender identifier of the network information in the information header of the network information; correspondingly, the client The terminal uses the updated setting information to filter the network information, including: when the client receives the network information forwarded by the sender, using the setting information locally stored by the client, the sender identifier and the original in the information header of the network information. The sender ID is filtered. The blacklist may include at least one of the following methods: a phone number, an email address, a client ID (identity, identifier), a network user ID, a network address Uniform Resource Locator (URL), and a media access of the terminal. Control (Media Access Control, MAC for short) address, Internet Protocol (IP) address, International Mobie Equipment Identity (IMEI) number, IMEI TAC (device model approval number) No., terminal user-agent (user agent) parameters and other identifiers. Therefore, the present invention is suitable for filtering network information such as voice calls, SMS, MMS, EmaiK multimedia mail, timely messages, and network messages. The embodiment also provides a forwarding mechanism, in which the information header of the forwarding information is newly set. The following is an example of the sending direction of the receiving party to the network in the sending direction: When the sending direction forwards the network information to the receiving party The sender or the server adds the sender identifier and the original sender identifier of the network information to the information header of the network information, and forwards the network information after the identifier is added; when the receiver receives the network information forwarded by the sender, The sender ID and the original sender ID in the header are filtered using the setting information stored locally by the receiver. The setting information stored locally by the receiving party may be only the blacklist of the receiving party. The blacklist of the receiving party may also be the blacklist extended by the foregoing method, that is, not only the blacklist of the receiving party but also the first blacklist. The blacklist obtained by the three parties. The sender identifier in the header of the network information is the identifier of the user corresponding to the sender, and the original sender identifier includes the identifier of the user who forwarded the network information before the sender and the identifier of the original sender of the network information. Therefore, the forwarder that previously forwarded the network information is considered to be the original sender of the network information with respect to the current sender. In addition, the addition of the sender identifier and the original sender identifier of the network information may be completed by the sender or by the sender/receiver server. This embodiment further provides another method for information filtering, which may be implemented on the server side. As shown in FIG. 3, another flow chart of the information filtering method includes the following steps (step S302-step S306). In step S302, the server receives the request message for obtaining the setting information from the client. In step S304, the server adds the setting information of the third party intercepting the spam information to the storage area corresponding to the client local to the server; wherein the third party is a client One or more devices other than the terminal; Step S306, when the server forwards the network information to the client, the network information is filtered by using the setting information in the storage area. After the server receives the request message for obtaining the setting information from the client, the server adds the setting information of the third party intercepting the spam information to the storage area corresponding to the client local to the server, and the server uses the setting information in the storage area to the network information. Filtering solves the problem of low efficiency of filtering spam in related technologies. This method expands the setting information of the client on the server, improves the success rate of filtering spam, and improves the user experience. If the client wants to obtain the setting information of another specified client, that is, the request message specifies the setting information of the client for the request, the server locally searches for the setting information corresponding to the specified client, and adds the found setting information to the client. The corresponding storage area on the server. Or the server sends a request message for the setting information to the specified client, and receives the setting information of the specified client, and then adds the setting information to the corresponding storage area of the client on the server. In this way, the client obtains the setting information of the specified client, expands the setting information of the server itself, and provides conditions for improving the success rate of filtering the spam. When the requested setting information is the setting information of the third-party server, the server forwards the request message of the setting information to the third-party server, and receives the setting information of the third-party server, and adds the setting information to the corresponding storage of the client on the server. Area. As in the above embodiment, the setting information herein may also include: a blacklist and/or a spam processing rule. The client expands the blacklist and/or spam processing rules by sharing the blacklist of the third party, and further augments the spam by augmenting the blacklist and/or spam processing rules. The expanded blacklist and/or spam processing rules may be stored locally as shown above, or may be stored in the server. The process of storing the expanded blacklist in the server is as shown in FIG. 4: Step S402, the client is in the server. Creating a blacklist on the first step; Step S404, the client sends a request message for obtaining a third-party blacklist to the server; Step S406: The server adds the third-party blacklist to the blacklist created by the client locally on the server. The expanded blacklist can be used to filter spam. The specific method of filtering can be solved by using existing technical methods, and will not be described here. Similarly, the process of processing the expanded spam processing rules stored in the server is also the same, and will not be described here. When the setting information is a blacklist and a spam processing rule, the server uses the setting information in the storage area to filter the network information to be forwarded: First, the server detects whether the sender of the network information to be forwarded is in the blacklist; Secondly, if the sender of the network information is in the blacklist, the network information is determined to be spam. If the sender is not in the blacklist, the server detects whether the network information has a keyword matching the spam processing rule. If the network information has a keyword matching the spam processing rule, the server determines that the network information is spam. After the server determines that the network information to be forwarded is spam, the spam is intercepted to prevent the spam from being sent to the client. For network information that cannot determine whether it is spam, it is usually simply processed according to normal information, or prompting the user to process, or detecting whether the sender of the information is in the white list, thereby judging whether it is friend information or strange information. If the network information to be forwarded to the client by the server is the information forwarded by the forwarder, it is assumed that the original sender of the network information is located in the blacklist of the server, and the forwarder is not in the blacklist. The spam information is not filtered out. In this case, the identifier of the forwarding party and the identifier of the original sender may be carried in the network information, and the server detects whether the identifier of the forwarding party and/or the identifier of the original sender is in the blacklist. If one of the identifier of the forwarder and the identifier of the original sender is in the blacklist, it is determined that the sender of the network information is in the blacklist, thereby determining that the network information is spam, and the server intercepts the spam, preventing the It is sent to the client. Corresponding to the above method for filtering information implemented on the client, this embodiment provides a client device for information filtering, which is used to implement the above embodiment.

Through the client device, the storage module 54 updates the locally stored setting information according to the setting information of the third-party intercepting spam information acquired by the obtaining module 52, and the filtering module 56 uses the locally stored updated setting information when receiving the network information. Filtering the network information solves the problem of low efficiency of filtering spam in related technologies. This method expands the setting information of the client, improves the success rate of filtering spam, and improves the user experience.

For spam. The implementation process of the above embodiment will be described in detail below in conjunction with the preferred embodiments and the accompanying drawings. Embodiment 1 When the receiver of the network information intercepts the received network information through the blacklist and/or the spam processing rule (that is, the setting information), sometimes the part of the spam information cannot be intercepted because the setting information of the receiver is small. In this case, for security reasons, the recipient expands its blacklist and/or spam processing rules by sharing third-party blacklists and/or spam processing rules (ie, third-party interception spam settings). The network information sent by the sender is processed using the extended blacklist and/or spam processing rules. The extended blacklist and/or spam processing rules can be stored locally on the client or on the server. The processing of these two storage methods has been described above and will not be described here. For the above scenario, for example, the social network user has his own blacklist/spam processing rule, and the social network user has a group of friends on the social network, and their friends each have their own blacklist/spam processing rules, the social network Users can use their blacklist/spam processing rules, as well as their blacklist/spam processing rules and/or third-party blacklist/spam processing rules to filter the received network information locally. For the scenario, the solution proposed in this embodiment is as shown in FIG. 11. FIG. 11 is a flowchart of a method for information filtering according to the first embodiment of the present invention. The method includes the following steps (step S1102-step S1106): S1102: The social network client requests the social network server to obtain a blacklist/spam processing rule of the social friend, and/or a third party blacklist/spam processing rule; Step S1104: The social network server provides the social network client with the blacklist/spam processing rule and/or the third party blacklist/spam processing rule of the friend. Step S1106: The social network client responds to the blacklist/garbage of the server. Information processing rules are added to the locally expanded blacklist/spam rule base. In the above manner, the social network client has expanded its own blacklist/spam rule base. When the network information is sent to the social network client, the client processes the network information according to the extended blacklist/spam processing rule, thereby improving the success rate of filtering the spam and improving the user experience. Embodiment 2 In the foregoing Embodiment 1, the social network user can use the blacklist/spam processing rule of the user, and the blacklist/spam processing rule of the friend and/or the third party blacklist/spam processing rule to filter locally. The received network information, this embodiment describes that in the same scenario as the above embodiment 1, the social network user utilizes his own blacklist/spam processing rules, and the friend's blacklist/spam processing rules and/or third parties. FIG. 12 is a flowchart of a method for filtering information according to a second embodiment of the present invention. The method includes the following steps (step S1202-step S1208): S1202. The social network client creates a blacklist/spam rule rule base on the social network server. Users can create an empty blacklist/spam rule base on the server through the client (to facilitate the addition of extended blacklist/spam rules in the future;). The social network client can also send the locally stored blacklist/spam processing rules to the server and add them to the blacklist/spam processing rule base corresponding to the social network client in the server. Step S1204: The social network client requests the social network server to obtain a blacklist/spam processing rule and/or a third party blacklist/spam processing rule of the friend. Step S1206: The social network server adds the blacklist/spam processing rule base of the friend and/or the third party blacklist/spam processing rule to the blacklist/spam processing rule base created by the user on the social network server. Step S1208: The social network server processes the information sent to the social network client by using the blacklist/spam processing rule base, and then sends the information to the social network client. In the above manner, the social network client expands the blacklist/spam processing rule base created on the social network server. When there is network information sent to the social network client, the social network server is based on the extended black name. The single/spam processing rule processes the network information, and then determines whether to send the network information to the social network client, thereby improving the success rate of filtering the spam and improving the user experience. The third embodiment assumes that the network information received by the user is information forwarded by the user's friend, and the network information may belong to the spam for the user (for example, the original sender of the network information is located in the user's blacklist), but In this case, the network information cannot be intercepted based on the existing blacklist mechanism. Therefore, this embodiment proposes a method for filtering information, as shown in the flowchart of the method for filtering information shown in FIG. 13, the method includes the following steps (step S1302 - step S1304):

S1302: The information forwarder adds the original sender identifier of the information to be forwarded to the information; S1304: The receiver filters the information according to the forwarder identifier and/or the original sender identifier. Through such transmission, the forwarded information includes the identifier of the forwarder and the identifier of the original sender. After receiving the information, the receiver may process the information according to the forwarder identifier of the information and/or the original sender identifier. For example, although the forwarding party is a friend of the user, the original sender may be in the blacklist of the user. For the forwarded information, the information may be intercepted by using the foregoing manner, thereby improving the success rate of filtering the spam and improving the user's Experience. Embodiment 4 For the method described in the foregoing Embodiment 3, it is assumed that the network user has his own blacklist and a group of friends. When the friend forwards the information to the network user, since the friend is not in the blacklist, the user usually does not Filtering a friend's information, but if the information is not spam for his or her friends, it may be spam for the user, for example, the original sender of the information is in the user's blacklist, for this case, This embodiment will describe in detail the processing procedure for the receiver to process the information according to the forwarder identifier of the information and/or the original sender identifier. FIG. 14 is a flowchart of a method for information filtering, and the method includes The following steps (step S 1402 - step S1404): Step S1402, the information forwarder adds the original sender address of the information to be forwarded to the information. Step S1404: The receiver processes the information according to the forwarder address and/or the original sender address in the information. For example, User B (mail address: b@test2.com) has a friend C (email address: c@test 3. com) forwards an email to User B (the original sender's address is a@testl.com) ), where a@testl. com is User B's blacklist. Assume the existing mail format (only some of the fields related to the present invention are given, and the specific header and body format can be consulted for related documents) as follows:

From: " test3 "<c@test3.com >

To: " test2 "< b@test2. com> Cc:

Subject: mail content

Date: Thu, 25 Oct 2011 13:38:31 -0800

MIME- Version: 1.0

Content-Type: multipart/mixed; Return-Path: c@ test3. com In this case, it can be implemented by adding the original sender's mail address in the From: field, and the new mail format is:

From: " test3 "<c@ test3.com > /" testl "<a@testl.com>

To: " test2 "< b@test2.com> Cc:

Subject: mail content

Date: Thu, 25 Oct 2011 13:38:31 -0800

MIME- Version: 1.0

Content-Type: multipart/mixed; Return-Path: c@ test3.com When the receiving user B (mail address: b@test2.com) receives the message, it extracts the From: field. The subsequent original address is compared with the blacklist to process the received information. For example, in the embodiment, the original sender's address a@testl.com is in the blacklist of user B. Filter and block this information directly. In addition, this step can also be implemented by adding a custom field (starting with X-) in the header. If the custom domain name is set to X-Transmit, the new message format is:

From: " test3 "<c@test3.com >

To: " test2 "<b@test2. com> X-Transmit: " testl "<a@testl.com>

Cc:

Subject: mail content Date: Thu, 25 Oct 2011 13:38:31 -0800 MIME- Version: 1.0 Content-Type: multipart/mixed;

Return-Path: c@test3.com When the server (test2) of the receiving user B (email address: b@test2.com) receives the email, it extracts the email address and blacklist in the X-Transmit: domain. For comparison, for example, in the embodiment, it can be known that the original sender's address a@testl.com is in the blacklist of user B, and the information is directly filtered and intercepted.
